Eaton — Wide Range of Thin Film Capacitors

Eaton’s Wide Range of Thin Film Capacitors

Tailored to various electronic applications and designed with specific features to meet stringent demands

Eaton’s range of film capacitors, including safety, DC-link, pulse, and AC filtering capacitors, offer a comprehensive suite of solutions for various electronic applications. Each capacitor type is designed with specific features to meet the stringent demands of their respective functions. Safety film capacitors are integral in suppressing EMI and withstanding overvoltage surges, ensuring compliance in safety critical applications like automobiles and medical devices.

Their high capacitance stability, self-healing properties, and flame-retardant construction make them a reliable choice for protecting against electrical noise and potential hazards. DC-link capacitors, known for their high capacitance density and self-healing metallized film construction, offer a robust alternative to electrolytic capacitors. They are suitable for smoothing voltage ripples and managing current flow in rectifiers and inverters, crucial for high-frequency power circuits. Eaton’s film pulse capacitors, including the EFPLS and EFPLA, offer high dV/dt handling and current capacity, self-healing capability, and ensure reliable performance in high-frequency power supplies and motor drives, with products meeting automotive reliability standards.

The EFACA film AC filtering capacitors are suitable for minimizing high ripple harmonic content, ensuring a stable power supply for power converters and inverters. Their durable construction and qualification for harsh environments make them suitable for a broad range of applications, including those in the automotive and industrial sectors.

Eaton’s portfolio of capacitors demonstrates a commitment to quality and reliability, addressing the needs of energy storage, filtering, and pulse power in various electronic applications. Each capacitor family offers unique benefits, ensuring that designers can find the right component for their specific application.

Film capacitors feature a thin dielectric layer between two metal electrodes to provide stability and reliability in electronic circuits. Often used in electric vehicles (EVs), renewable energy systems, and consumer electronics, these components contribute to energy storage, peak power delivery, and voltage stability.

Features

Self-Healing Capability: The metallized polypropylene film construction allows the capacitors to recover from dielectric breakdowns, enhancing longevity and reliability.
High Capacitance Density: Eaton's DC-Link capacitors offer capacitance values ranging from 1.0 µF to 200 µF, providing efficient energy storage in compact forms.
High Ripple Current Handling & Low Loss: Designed to manage substantial ripple currents with minimal energy loss, making them suitable for power-intensive applications.
Thermal and Environmental Robustness: Operating temperature ranges from -40°C to +105°C, with certain models qualifying under THB Grade IIIB and AEC-Q200 standards for automotive and harsh environments.
Flame-Retardant Construction: Safety capacitors feature flame-retardant plastic cases and resins, meeting UL94V-0 requirements for enhanced safety.

Applications

DC-Link Capacitors: Used in frequency converters, industrial power supplies, solar inverters, uninterruptible power supplies (UPS), AC motor drives, air conditioners, and switch-mode power supplies (SMPS).
Safety Capacitors: Employed for electromagnetic interference (EMI) suppression in Class X1 and X2 applications, including across-the-line filtering in power supplies and appliances.
Pulse Capacitors: Designed for high-frequency and high-pulse applications such as onboard chargers (OBC), electric vehicle (xEV) traction inverters, DC-DC converters, and xEV chargers.
AC Filtering Film Capacitors: Found in power converter circuits for filtering harmonic content in input and output signals and as a voltage modifier and stable over temperature, frequency and time. AC Filter capacitors are commonly used in inverters, energy storage systems, motor drives, industrial machinery, battery chargers, and are ideal for automotive applications.
